Pending analysis
Type:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> PM: EM: Fix potential division-by-zero error in em_compute_costs()<br /> <br /> When the device is of a non-CPU type, table[i].performance won&amp;#39;t be<br /> initialized in the previous em_init_performance(), resulting in division<br /> by zero when calculating costs in em_compute_costs().<br /> <br /> Since the &amp;#39;cost&amp;#39; algorithm is only used for EAS energy efficiency<br /> calculations and is currently not utilized by other device drivers, we<br /> should add the _is_cpu_device(dev) check to prevent this division-by-zero<br /> issue.
